Infopath Forms dont display in browser

I am new to Infopath and am having trouble displaying infopath forms on ourdevelopment MOSS Enterprise server. I followed the steps here to create anew infopath form and publish it to the server. But when I browse to mydocument library and select New--> MyTemplateName, I get the popup saying'Loading Form', and then the Browser windows displays a bunch of garbagecharacters

I am able to display forms on our production server however. So I startedfiddler and browsed to my production library and created a new documentbased on the production form template. The response in fiddler looks likethis from my production serever:
